explode?

[Anon]

how can I break a string up by charictor I tried
$string = "this is cool";
$charictors = explode("", $pizza);

hoping to return the values
"t","h","i","s"," ","i","s"," ","c","o","o","l"
but no sucess... how can I do this... or is there a better way?
I plan to use it to deveolop an encryption key... any ideas?

Thanks In Advance

like in C string are simply character arrays. so you can access them like nn array.

$ex = \"this is a string\";
echo $ex[5]; // "i";

i guess i dont use it much. can you use all basic array function on string i dont think but you could reassign a string to a real array if neccesary.

If you do want a proper array of characters, there is a snippet of code in the PHP documentation which runs:

$chars = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);

Which does the job.
